A field experiment was carried out at Department of Agronomy, Anbil Dharmalingam Agricultural College and Research Institute, Trichy during Rabi, 2018 to study the effect of different weed management practices on nutrient removal, nutrient uptake andgrain yield of transplanted rice. The experiment was laid out in split plot design with four main plot and five sub plot treatments and replicated thrice. The experimental plot size was 20 m 2 . Main plot treatments were pre plant application of herbicides namely, glyphosate 2.5 kg ha-1 , glufosinate ammonium 1.0 kg ha-1 ,halosulfuron methyl 67.

Plants are exposed to a various biotic and abiotic stresses that can affect either directly or indirectly the photosynthetic performance of leaves. Several imaging techniques have been used to detect the early signs of stress by monitoring changes in water status, photosynthetic performance or structural modifications.

To meet the food requirement of a huge population the food grain production need to be enhanced accordingly. However the goal of higher production must not come at the cost of heavy exploitation of natural resources. In order to attain higher yields, need of the hour is to develop and promote new technologies and reform agricultural research. Nanotechnology holds promise in improving the fertilizer use efficiency of fertilizers. The unique properties can be exploited beneficially for improving the nutrient use efficiency.

A field experiment was conducted to assess the effect of seeding methods and weed management practices on yield of aerobic rice and nutrient removal by the weeds under direct seeded aerobic rice. Among the seeding methods line sowing increased the grain yield than the broadcasting method. Among weed management all the weed management practices were found to be equally effective in reducing the uptake of nutrient by weeds and producing higher grain yield as compare to weedy check. However maximum yield was obtained with the application of Pretilachlor 0.

Weeds are undesirable plants out of place and function as an uneconomic tax on the crop by taking the space required for the plant, absorbing the water and nutrients from the soil and by competing for other essentials like light, moisture etc. There are two methods generally employed for controlling weeds. viz., (i) Hand weeding, and (ii) Use of herbicides. In India, the first one is generally practiced by the farmers. This method is the most labour intensive and costly.

The use of herbicides in rice may affect the soil‟s biological equilibrium and thus influences its nutrient status, health and productivity. To know about the effect of herbicides on soil microbial populations in rice, a field experiment was conducted at Palampur during kharif 2016 and 2017. Ten treatments, comprised of company released sample of pyrazosulfuron-ethyl 10% WP at 10, 15, 20 and 30 g ai/ha was compared to market sample at 10 and 15 g/ha, bispyribac- sodium at 20 and 40 g/ha, hand weeding twice and weedy check on a silty clay loam soil.

The study was conducted during 2018-19 in Mandya district of Karnataka State, India. The pre-tested interview schedule was used to collect the data from 120 Seasamum growers through personal interview method. The collected data was tabulated and analyzed using percentages, correlation and regression. As high as 44.17 per cent of Seasamum growers belonged to medium level adoption category, 35.00 per cent to low adoption category and 20.83 per cent belonged to high adoption category.

It was examined that weeds cause a lot of problems in the crop field. Weeds compete with the main crop for nutrients, water, food, space, sunlight etc. Weeds utilize the nutrients provided to the main crop and sometimes dominate the main crop. Some weeds are very noxious and they are harmful for both humans as well as animals. It is clearly revealed from studies done in field of weeds that use of herbicides used to control weeds cause many effects on soil as it leads to degradation in the quality of soil, water as well as it pollutes environment.

Weed is a plant growing where it is not desired so weeds are ubiquitous. The vegetable fields are usually infested by a wide spectrum of broad and grassy weeds. Weeds compete with the crops for water, soil, nutrients, light, space and crop yields are significantly reduced as reported by several studies. The vegetable as well as agricultural crops are infested with a variety of weeds. Out of over 800 weeds documented in India, 80 are considered as serious and nearly 200 as major weeds. They also harbour many insect-pests and microorganisms.

Agriculture is the most important sector of the economy in India as it provides food and livelihood security. The industrialization of agriculture has favored the use of plenty of agrochemicals including fertilizers, pesticides, micro nutrients, and plant growth regulators in the agricultural fields. Pesticides are an integral part of modern agriculture. The use of pesticides in agriculture is obvious for the prevention of crop-damaging pests, fungus, unwanted plants (weeds) and a number of crop-eating animals like rodents etc.

Unnecessary weed growth in sugarcane fields forces plants to compete for nutrients and sunlight for survival, which most often leads to significant yield losses. As chemical herbicides cannot differentiate between crop plants and weeds, the development of herbicide-tolerant crops is anticipated.

There is currently no independent authoritative statement on the nature and importance of differences in content of nutrients and other nutritionally relevant substances (nutrients and other substances) in organically and conventionally produced foodstuffs. This systematic review of the available published literature was designed to seek to determine the size and relevance to health of any differences in content of nutrients and other substances in organically and conventionally produced crops and livestock products.

Given the large and increasing demand for organic foodstuffs in the UK and elsewhere, an up-to-date objective independent statement on the nutrient and other nutritionally relevant substance composition of organically and conventionally produced foodstuffs is needed for both public policy and consumer advice. The aim of this report is to systematically review and compare the composition of organically and conventionally produced foodstuffs, focusing only on nutrients and other nutritionally relevant substances (nutrients and other substances).
